What Is Venous Thromboembolism?

Deep vein thrombosis (DVT), which happens when a blood clot forms in a vein deep below your skin, often in the legs. If a clot breaks loose, it can travel to your heart, lungs, or brain. This blocks blood flow to these vital organs and can lead to life-threatening complications.

Pulmonary embolism (PE) happens when a blood clot breaks loose and blocks an artery in the lungs, which can be life threatening.

Venous thromboembolism risk factors and causes

You can either inherit or acquire a VTE.

A VTE results from slow movement of blood through the veins, which can stop flowing freely and cause a clot to form.

Anyone can have a VTE, but some risk factors include:

Being idle during an extended hospital stay.

Long periods of travel, especially on an airplane.

History of blood clots.

Estrogen-based drugs (birth control or hormone replacement therapy).

Cancer treatment.

Obesity.

Pregnancy or recently having a baby.

Smoking.

Venous thromboembolism complications

VTEs can lead to serious health problems that can be fatal, including PE and stroke.

Treatment and follow-up care are vital to help manage long-term complications, such as:

Post-thrombotic syndrome.

Chronic thromboembolic pulmonary hypertension.

If you or someone else suspects a blood clot, contact a medical professional right away.
